Miley Cyrus linked to a TwitPic from Grease and wrote: "RIP Jeff Conaway. I'll see you in another life."

Eva Longoria wrote on the microblogging site: "My fav Grease quote is, 'A hickey from Kinickie is like a Hallmark card.'"

Conaway passed away at 10:30 a.m. Friday morning, his manager, Phil Brock, confirmed to Us Weekly in a statement. "He was taken off life support yesterday afternoon. His sisters, nieces, nephews and ministers were by his side when life support was removed."

The actor, 60, was hospitalized on May 11 for what was initially thought to be a prescription drug overdose. It was later revealed that he was suffering from pneumonia and sepsis, a dangerous blood infection. He remained in a comatose state for over two weeks until his death.

In the 1978 classic musical, "Grease," Travolta, 57, played Danny Zuko, and Conaway played his confidant, Kenickie. Conaway was even married Rona Newton-John, the sister of his "Grease" costar, Olivia Newton-John, from 1980 to 1985.
